No. The xintercept is the place where the line meets the xaxis; you find it by setting y=0: 0=m*x+b, so x = b/m. So the xintercept is b/m (or the point (b/m, 0) on the xaxis). The yintercept is the place where the line meets the yaxis; you find it by setting x=0: y= m*0+b = b. So the yintercept is b (or the point (0,b) on the yaxis). For example, if you consider the line y=3x1, the xintercept will by 1/3, and the yintercept is 1.
